Step 1
Step 1: When two wave pulses completely overlap, if they are in phase (constructive interference), the amplitudes of the two pulses will add up to create a larger amplitude in the resultant wave. Show more…

2. Which diagram best represents the wave formed when the two pulses meet?
Two pulses of different amplitudes approach each other, each having a speed of $v=1.00 \mathrm{m} / \mathrm{s}$ . Figure $\mathrm{P} 18.4$ shows the positions of the pulses at time $t=0 .$ (a) Sketch the resultant wave at $t=2.00 \mathrm{s}, 4.00 \mathrm{s}, 5.00 \mathrm{s},$ and $6.00 \mathrm{s}$ . (b) What, If? If the pulse on the right is inverted so that it is upright, how would your sketches of the resultant wave change?
